| Abstract Scope |
This study investigates the fabrication of heterogeneous steel alloy using an in-house developed Gas Tungsten Arc Welding (GTAW) based multi-wire arc additive manufacturing (M-WAAM) setup. The process employs Mild Steel ER70S-6 and Stainless Steel 304 (SS304) as feedstock materials, merging their unique properties to achieve specific alloy compositions. The in-house multi-wire setup allows for the simultaneous deposition of these materials, providing flexibility and precision in alloy fabrication. It explores the compatibility of ER70S-6 and SS-304 during deposition, focusing on interlayer bonding and chemical interactions to ensure alloy homogeneity. It evaluates the impact of heterogeneity on microstructure, affecting properties such as tensile strength and hardness. This heterogeneous alloy composition exhibits superior hardness and tensile strength compared to its parent materials. These alloys have applications in the aerospace and automotive industries, highlighting their potential for high-performance component manufacturing. |
